this is a beat/instrumental tape consisting of only @adelemusic and @gorillaz samples. the title derives from adele's first two albums '19' and '21' and also the gorillaz' track 19-2000, which i renamed as 19-2100 as to keep consistent with the title theme. Also there are 19-21 tracks on this tape, give or take (missing a few because of copyright issues). enjoy.
